Philosophy 185 Heidegger

Lectures from the course Philosophy 185 Heidegger by Hubert Dreyfus. Copied to on closure of the UCB podcast site in order to preserve access. Note: some lectures may appear to be missing (gap in numbering). This usually means that there was a holiday or no lecture on the day the recording was due, although sometimes it does mean that the audio is not available. Course Description:
Philosophy 185 - Fall 2007 - One of the most important philosophical works of the twentieth century, Being and Time is both a systematization of the existential insights of Kierkegaard and Nietzsche and a radicalization of Husserl's phenomenological account of intentionality. What results is an original interpretation of the human condition leading to an account of the nature and limitations of philosophical and scientific theory. This account has important implications for all those disciplines that study human beings.

Lecture 3:
The professor doesn't want the equipment added to substance because it is not self sustained and yet nothing is really self sustained except for the suprasubstance (Being). So why not put the equipment into the substance grouping or add an additional category and call the category "Dasein Created" where all equipment is "Dasein infected". The hammer is created by Dasein for hammering, the eye is used by Dasein for seeing, booze or peyote are used by Dasein for seeing, the brain is used by Dasein for thinking (and sometimes being rational) and Dasein is used by Dasein for intellecting, etc. all of which could be consider as Dasein infected.

Intelligibility does seem holistic and immaterial, an essential quality for Dasein to possess in its being, but surely there must be a kind of being that is Being where all the small Dasein beings sit within the Being.

We don't understand the background of being MH says. But I would think that when the genetic potentiality for reason (substance) comes in contact and combines with the actuality of the senses (substance) it leads to the potentiality and actuality of equipment (Dasein-infected substance) and also the self awareness of Dasein with itself and for the very few the self awareness of Being itself (the truly fundamental ontology)

There is a mention of Dasein not having to think about negotiating the world because it possesses know how yet this seems incorrect. Dasein must always be thinking; be it overt or covert, consciously or subconsciously. Nothing that involves a calculation of being can occur with out movement and with movement thereby intelligibility and thinking.

When it is stated that Dasein eventually possesses forstanding isn't this just like saying that it uses the background (mentioned below) to predict the behaviour of being (not Being itself).

It might have been better if the translator had used rationalizing instead of understanding but maybe that's just a personal preference.

I do like it when he says that when we are lost in a task we become equipment and not Dasein. This makes me think being phenominologically and ontologically shimmers back and forth for a Dasein.

There is talk of the background to being and the claim that it cannot be described where MH will attempt to describe it. But isn't this background just the natural rational rules presented to us in contrast to the irrational conduct of human thought . All life is rational except Dasein because of its free will and so when you see Dasein use the rational background of substance it proves that it is describable. You must have the irrational set beside the rational to see the being of the rational because without the irrational the rational background would still exist but it could never be known or seen.

Subject: Excellent
Excellent series of lectures.
Be ready! You have to have the book of Heidegger at hand all the time. Each lecture takes more than 2 hours of real time - you are listening, then listening again, then you stop in order to read the book and so on.
It's rather hard work but very enjoyable one. It's worth to listen.
